Water-based seal white primer

Abstract

The invention relates to the technical field of woodenware seal primers, and particularly discloses a water-based seal white primer. The white primer is characterized in that the white primer containsthe following components in parts by weight: 30-50 parts of water-based polyurethane resin; 30-40 parts of water-based hydroxyl-terminated silicone resin; 15-30 parts of titanium dioxide; 45-60 partsof water-based silicon resin; 1-5 parts of silica powder; 1-10 parts of transparent powder; 1-10 parts of zinc powder; 3-10 parts of ethylene glycol monobutyl ether; 5-13 parts of deionized water; and 5-13 parts of absolute ethyl alcohol. Water-based polyurethane resin and water-based hydroxyl-terminated silicon resin permeate into wood and are crosslinked and cured to form a compact paint film tightly combined with the wood, so that pores of the wood are sealed and blocked, the crosslinking density is further improved through the water-based silicon resin, the sealing effect is improved, andsilicon micro-powder, transparent powder and zinc powder are combined, so the white filling and sealing material with good fluidity, high strength and high whiteness is formed; the use amount of subsequent white primer is effectively reduced while the filling and sealing effect is ensured, and the sealing treatment process is simplified.

Description

technical field [0001] The invention relates to the technical field of wood sealing primers, in particular to a water-based sealing white primer. Background technique [0002] In the finishing of wood products such as wooden doors, windows, furniture, etc., the base treatment of wood embryos is very important. Its main function is to fill the gaps and seal the board surface, and seal the extravasation of chemical substances such as oil, pigment, protein, and tannin in the wood. , Effectively prevent wood cracking, paint film bulging, cracking and other problems after long-term use, and at the same time make the paint surface smooth, achieve a good coating effect, and save the amount of subsequent paint. In the prior art, atomic ash and pig's blood ash are often used as primer ash materials. However, these primer ash materials need to be adjusted and used immediately, with many procedures, unsatisfactory filling and sealing effects, and insufficient surface smoothness. Probl...

Problems solved by technology

In the prior art, atomic ash and pig's blood ash are often used as primer ash materials. However, these primer ash materials need to be adjusted and used immediately, with many procedures, unsatisfactory filling and sealing effects, and insufficient surface smoothness. Poor strength and other problems, and none of them are white, and in the existing wood product finishing, white primer is often used, which makes it necessary to use more white primer to cover the wood embryo body
